Messed up zoom navigation, need help!
I found out what exactly went wrong here. The view was locked to the object. So I somehow pressed a key combination that made the current object be the target for locked view.

If this occures to anyone else, press N whilst your mouse cursor is in 3D view window. Scroll through the opened panel, until you find the "view" one.



Now delete the target by clicking on the "x" as shown in the picture. This solved my problem.
